Title: Werner Pohl and a Circuit for Measuring Current in Reversible DC Controllers.

Introduction

Werner Pohl is an inventor associated with Vienna, Austria, and Siemens Aktiengesellschaft. His patent describes a circuit arrangement designed to determine both the polarity and magnitude of load current in a reversible direct-current controller.

Latest Patents

Pohl’s listed patent, “Circuit Arrangement for Determining the Polarity and Magnitude of the Load Current,” uses a bridge circuit with bypass paths across the load. During pauses in the load drive, the current circulates through alternating bypass circuits. Current transformers and electronic switching circuitry produce a pulse train whose polarity indicates the direction of the load current. A further embodiment uses a sample-and-hold stage to determine the current’s magnitude and polarity. Pohl is credited with 1 patent.

Career Highlights

Pohl’s documented patent work is connected with Siemens Aktiengesellschaft. The invention addresses current measurement in reversible DC control systems, including the challenge of detecting current when the load drive pauses.

Collaborations

Franz Ramlohr and Walter Kolzer are identified as Pohl’s coworkers. The available information does not specify their roles in developing or patenting this circuit.

Conclusion

Werner Pohl’s patent presents a method for determining load-current polarity and magnitude in a reversible DC controller, combining bridge circuits, current transformers, and electronic signal processing.
